flhis invention relates to improvements in wiper arrangements formirrors and the like, lt' is an object of the invention to provide a, wiper arrangement including a mirror, an arm pivoted adjacent the margin of the mirror, a second arm pivoted on the first one, and a Wipe ing element carried by at least one of the arms so that as the latter are moved along aguided path substantially the entire surface of the mirror'is wiped. v

,Another object of the invention is to provide such a wiper arrangement case wherein the arms are so arranged that when their movement in either direction is completed only a very small portion of the mirror is obstructed.

V A: further object of the invention is'to provide such a wiping arrangement wherein an annular member is provided around the mirror to which one extremity of one of the arms is pivoted, and wherein a'guideway is formed around a portion of the said member along which a pin extending from the second arm is 'slidable'to insure movement of both arms along a predetermined course whereby substantially the entire face of the mirror is wiped by wiping means carriedby at least enact the arms as the said pin is moved from one extremity of the guideway to the other.

Having'thus briefly stated-some of the objects and advantages'of the invention I will now describesome preferred embodiments thereof with the aid of the accompanying drawing, in which:

Figure 1 is a plan view'of a portion of a vanity case "open showing the mirror mounted therein andthe wiping means therefor.

-Figure2 is a view similar to Figure l but with thewiping means moved to a different position over the mirror.

Figure 3 is an enlarged section on the line 3--3 of Figure 2.

Figure 4 is a detail showing a portion of the guide member, and

Figure 5 is an enlarged section on the line 5-5 of Figure 4.

- .Figure 6 is a section on the line 6-6 of Figure 2.

Referring first to Figures 1 to 6 inclusive, l designates a circular vanity case or compact having a casing 2 and cover 3 which are hingedly connected at 4, and formed around their margins are forwardly projecting annular flanges 5 and a 6 respectively which engage one another when the vanity case is closed; Adhesively secured to the inner face of the cover 3 is a mirror Land mounted within the annular flange 6 is an annular guide member 8. The latter includes a circular flange 9 which bears against and is 5 Claims. (01. 15455) suitably secured to the inner face of the flange 6,,a retainer In which extends inwardly from and at right angles to the flange 9,, substantial y flush with the outer edge of the flange}, and around the greater portion of, its diameterpthe innenedge of the retainer isfolded parallel with the flange 9 toward the mirror ,to form astral: low'stopv l l.. Thus around the greater portion-of the circumference of the casing the flange ,8, retainer I0 and stop [1 form a guideway 12. .j A

segmental portion of the guide ,member ,8 con-,- necting the extremities of the-guideway ll-cisof angle section and consists merely of the flange 9 and a retainer portion lllofgreaterwidth than the retainer l0 and straight across its inner margin. 'Pivotally mounted on andbeneath the retainer portion--10? adjacent the flange 9 .fand substantially centrally between the ends of the guideway I2 is one extremity ofan arm I 3.. Formed in the inner face of the retainer portion l0 between the pivot mounting of the arm'l3 and the axis of the cover 3iis a depression H to engage a corresponding projection [5 formed on the arm l3 which is somewhat resilient. Pivoted on the opposite extremity of the arm I3 is a sec-'- ond arm 16 having a pin I! extending through its outer extremity and in engagement with the guideway l2, which'tends to force-the somewhatv resilient arm l6 against the mirror 1. Secured along the underface'of the arm IS in contact with the mirror 1 is a wiping element [8 which usually consists of felt or chamois." In thisinstance the arm H5 is longer than the arm l3 and has an outwardly projecting knob I9 secured thereto adjacent the pin ll. 'Itwill be seen. in Figure 1 that practically the entire face of the mirror"! within the guide member 8 is exposed,- that thearm l3 lies very largely beneath vthe retainer portion I0, and that the second arm li lies substantially parallel with the inner margin of the said retainer portion and adjacent there? to. By moving the arm'lB so that the pin;l1 travels aroundthe guideway l2 ina clockwise die motion, as indicated by the arrows A in Figures l and 2, through the positions indicated atB and C to its'position indicated at D in Figure 2,

the entire exposed portion of the mirror I is wiped by the wipingelement 18. Moreover upon arrival of the arms l3'and 16 at their positions indicated at D they are again beneath or adjacent the retainer portion l0. 3

The purpose of the coactingdepression l4 and projection 15 isto tend to retain the arm 13 in its position shown in Figure 2 when the two arms l3 and 16 are in alignment and extend diametrically across the mirror I. In that way the arm I3 is held against movement about its pivotal connection with the arm l6 until the latter is moved sufficiently to one side or the other of its position shown at C to force the said pivotal connection in the desired direction whereupon disengagement of the projection from the depression l4 occurs. Without the coacting depression l4 and projection I5 it would be possible for the pivotally connected ends of the arm 13 and I6 to'swing againto the right instead of to the left as the arm 16 is moved from its position C in a clockwise direction. Should that happen the movement of the pin 1! around the guideway.

would be stopped long before it reached its position l1 and the arms l3 and I6 would-obstruct an appreciable portion of the mirror "I. 'It will also be noted that the retainer-portion l0 exerts inward pressure against the arm [3 and that the stop II also exerts inward pressure, that is, 'towardthe mirror, against the arm l6, and since both these arms are somewhat resilient, the wiping element is retained in contact with the mirror Tat all-times, I
